Start from a known, safe scenario by verifying the default Switch and Jumper settings. You can then set switches / jumpers for your application.

a. GMII

J66 1-2

J67 1-2

J68 no jumper

b. FMC Bypass

J18 1-2 (bypass FMC LPC connector)

J17 1-2 (bypass FMC HPC connector)

J69 1-2 (near Compact Flash connector)

c. System Monitor

J19 1-2 (Test_mon_vrefp sourced by U23, REF3012)

J35 9-11 (measure voltage on R-kelvin on 12V rail)

J35 10-12 (measure voltage on R-kelvin on 12V rail)

d. SFP

J54 1-2 (Full BW)

J65 1-2 (SFP Enable)

e. PCIe Lane Size Select

J42 1-2 (nearest PCIe fingers)

f. System Ace Error Disable Jumper

Power on Test LEDs Status (below) are indications of Board health.

Check that the FAN spins.

Check the status of the following LEDs at Power ON, if not, try reset the TI power controllers using the XML script. See (Xilinx Answer 39037):

DS25 - 12V PWR - ON

DS30 - SYSACE CF error LED (blinks red with No CF card)

DS32 - FMC PWR Good - ON

DS28 - MGT AVTT - ON

DS27 - MGT AVCC (under LCD) - ON

DS29 - DDR3 PWR Good (under LCD) - ON

Check 6 Ethernet LEDs near RJ45 Ethernet jack P2. Cycle Power ON and OFF and see that all LEDs blink.

Check 12V Power LED is Green; if not, follow these steps:

Check the JTAG chain is initialized properly. If not, follow these steps:

Verify switch S2 settings:

S2.1 = OFF

S2.2 = ON

S2.3 = ON

S2.4 = OFF

S2.5 = ON

S2.6 = OFF

For JTAG configuration mode

Verify FMC bypass jumper positions J17 and J18.
Pin 1 and 2 to be connected by jumper in case FMC card is not present.
If using an FMC card, still try with jumpers on pin 1 and 2 of J17 and J18. If this works, then there might be an issue with the FMC connector.

Run ML605 Built-In Self Test Application Test 9 to check for errors; see XTP056 for more details.

Configuration is OK, IBERT not working:

Verify S2 switch is set to 0101XX.

Verify S1 switch set to 0XXX.

Check SMA loop back cable used correctly (if using MGT loopback). When using an SMA cable, connect J28 to J26 and J29 to J27.

Download and run rdf0066.zip and XTP091(whichever version is appropriate for silicon and software version, i.e., xtp091_13.2_c.pdf and rdf0066_13.2_c.zip for 13.2 ISE and Production Silicon) from the ML605 Reference Designs page.
